Umahluko phakathi kwe-pei kunye ne-peek

I-Pei ndibhekisa kwiPolyetherimide (Polyetherimide), ekwasisishwankathelo se-Polythyethyleiimide kunye neNdawo esebenza kakuhle yabasebenzi. I-Polyetherimide, iPolyetherimide ifinyeziweyo, i-amber-qual eqinile eqinile iflethi yeflethi kunye nesalathiso se-I-47%, i-il-starm ye-IL94-V-0, kunye ne-1.42 g / cm3.

I-Polyngunetone Ukuxhathisa, ukunxiba akuyonto eyomeleleyo ye-witric, ukuchasana kwe-radiation, iipropathi zoomatshini obalaseleyo zinokusetyenziswa kumatshini wokugqibela kunye nokuhamba ngenqwelomoya kunye nenye itekhnoloji.

1. Yintoni i-pei? Yintoni i-Peek?

I-Peek: Iplastiki yobunjineli be-thermoplastic enezinto ezibalaseleyo, iqulathe iipesenti ezi-4 zokugqibela okanye amaqela e-calbox okanye amaqela e-calxx I-Peek ingaba nokuchasana nobushushu obufanelekileyo, uzinzo lwamachiza, ukuxhathisa i-oxidation kunye namandla omatshini. Inendawo yokunyibilikisa engama-342 ° C kunye neqondo lokugcina i-thermal eyi-340 ° C, ethi iyenza ilungele indawo yobushushu obuphakamileyo. Ukongeza, i-Peek inee-inshulekiso zombane kunye neepropathi ezihlawulelweyo.

I-Pei: I-Pei yi-copolymer ye-Peek kunye neqela lezinye iipolymers, ngokwesiqhelo ezinama-35- 46% i-Peek kunye ne-65-75% ezinye iipolymers. Iipropathi zika-Pei ziwela phakathi kwezo zabaphathiswa ze-Peek kunye nezeNeras ezinjenge-PA66 kunye ne-PA6. Indawo yokunyibilika ye-pei iphezulu nge-290 ℃, kwaye amaqondo obushushu omhlaba aphezulu ukuya kwi-248 ℃.

2. I-Pei kunye ne-Peek kwiinkalo ezahlukeneyo zomehluko

. I-PEI inokugcina iipropathi zayo kunye nokuzinza kwamakhamamikhali kumaqondo obushushu aphezulu, ngelixa i-peek iya kuthamba, ukuhamba kunye ne-oxidation kumaqondo obushushu aphezulu.

. Umzekelo, i-Pei inamandla amanqam angaphezulu okanye ukuqina kune-peek. Nangona kunjalo, lo mahluko awubalulekanga kwizicelo ezininzi, kwaye ngenxa yendawo ephezulu yokunyibilika kunye nokuhamba okuhle, kunokuba luncedo ngakumbi kwinkqubo yokubamba.

Isishwankathelo, uPei kunye ne-Peek bangama-oriya osebenza phezulu kwitrastikhi yobunjineli obufanayo ngeendlela ezininzi, kodwa baneemahluko ezininzi eziphambili.
